Abstract (en)
[origin: WO2019121350A1] The invention relates to a force transmission device with a parallel guide comprising a movable parallel limb, a fixed parallel limb, a first parallel guiding element and a second parallel guiding element, wherein the parallel limbs and the parallel guiding elements are connected to each other by thin-point flexional bearings, wherein the movable parallel limb is guided by the parallel guiding elements on the fixed parallel limb. The force transmission device further comprises a force transmission lever, which is arranged on the fixed parallel limb and has a lever bearing, and comprises a first lever arm, wherein the force transmission lever is pivotally mounted on the lever bearing and the first lever arm of the force transmission lever is connected to the movable parallel limb in a force-transmitting manner, wherein the force-transmitting connection is effected by means of coupling element with at least one further thin-point flexional bearing. The force transmission device or at least a functional region of the force transmission device is designed monolithically, and a functional region of the force transmission device consists of the first parallel limb, and/or the second parallel limb, and/or the force transmission lever and/or the coupling element, and of the corresponding adjacent bearing points. The invention is distinguished in that the force transmission device or at least one of the functional regions consists of at least one first material, and at least one of the bearing points of the force transmission device or the at least one functional region consists of a second material.
